The reason is that the parse_uri function returns host:port in what was labeled the "domain" variable in 1.8 when in 1.4 the parsing was done in each individual function and the port truncated manually. For example, peer->fromdomain could be set to a host:port, even though it is specifically split into peer->fromdomain and peer->fromport other places in the code.

This patch does two things: 1) it renames the "domain" variables in the API functions to "hostport" to more accurately reflect what we are really returning and 2) implements a truncate_hostport function and uses it where appropriate.
